Get yoursef a REAL Caravan!! :-D

Combine SRM Companion Cart with Dragonkiller Cart and Better Horses and you are good to go ;-)

How to do this? Follow me:

1. Install all 3 mods MANUALLY (that is what I did anyway).

2. Set load order:
srmcompanioncart.esp
xgfPferdeKarren-en.esp
It_better_horses.esp

3. By the Companion Cart.

4. Set your horse to follow with the Better Horses command. (see mod specs)

5. Make a harness for the Dragonkiller Cart and tether your horse to it. (see mod specs)

6. Get on the Companion Cart and start driving.

Now your horse should follow nicely behind pulling the Dragon Cart just like in the picture I added :-)

Oh, no other horse effecting mods than More Saddels and Horses for Followers installed. And NO fast travel.

Recommeded to add lines below in Skyrim.ini for better Cart behaviour:

[Cart]
fWheelAngDamp=0.0100
fMass=300.0000
fFriction=100.0000
fGravMult=7.0000
fTipImpule=10000.0

I hope this might work with UFO aswell. I have not used it so far and I know it effects horses and works with the cart mods, but you never know.. Try it out and report here, or to the modders involved.

Pointer; With Better Horses you Sneak then E-klick for horse inventory and that works fine with this combo, BUT the horse inventory via Dragonkiller Cart is another _separate_ inventory and it is there you put the harness (and saddels/horsearmour who work nicely too) that comes with the Dragonkiller Cart mod.

Enjoy! I just loved it when I got this little caravan working :-D
